PROCEDE DE FABRICATION D'UN DISPOSITIF DE FILTRATION D'AIR ET DISPOSITIF FABRIQUE GRACE A UN TEL PROCEDE

摘要

The method involves assembling a filtering media (12) e.g. gas filter, with longitudinal air channeling walls (14, 16), and assembling a gripping element (20) i.e. flexible tab, of air filtering device (10) between the filtering media and the longitudinal air draining wall by infrared soldering, where the wall is made of polypropylene foam. The gripping element is fabricated by cutting the element in a scrap of material band utilized for fabricating the filtering media. An independent claim is also included for an air filtering device comprising a filtering media connected to an air channeling wall.
